Before commencing the installation
• Disconnect the power supply of the device.
• Ensure that devices cannot be accidentally
restarted.
• Verify isolation from the supply.
• Short circuit to earth.
• Cover or enclose neighboring units that
are live.
• Follow the engineering instructions (AWA)
of the device concerned.
• Only suitably qualified personnel in
accordance with EN 50110-1/-2 (VDE 0105
Part 100) may work on this device/system.
• Before installation and before touching
the device ensure that you are free of
electrostatic charge.
• The functional earth (FE) must be
connected to the protective earth (PE) or
to the potential equalization. The system
installer is responsible for implementing this
connection.
• Connecting cables and signal lines should
be installed so that inductive or capacitive
interference does not impair the automation
functions.
• Install automation devices and related
operating elements in such a way that they
are well protected against unintentional
operation.
• Suitable safety hardware and software
measures should be implemented for the
I/O interface so that a line or wire breakage
on the signal side does not result in
undefined states in the automation devices.
• Ensure a reliable electrical isolation of the
low voltage for the 24 volt supply. Only
use power supply units complying with
IEC 60364-4-41 (VDE 0100 Part 410) or HD
384.4.41 S2.
• Deviations of the mains voltage from the
rated value must not exceed the tolerance
limits given in the specifications, otherwise
this may cause malfunction and dangerous
operation.
• Emergency stop devices complying with
IEC/EN 60204-1 must be effective in all
operating modes of the automation
devices.Unlatching the emergency-stop
devices must not cause restart.

Safety instructions
Warning!
Dangerous electrical voltage!

• Devices that are designed for mounting in
housings or control cabinets must only be
operated and controlled after they have
been installed with the housing closed.
Desktop or portable units must only be
operated and controlled in enclosed
housings.
• Measures should be taken to ensure the
proper restart of programs interrupted after
a voltage dip or failure. This should not
cause dangerous operating states even for
a short time. If necessary, emergency-stop
devices should be implemented.
• Wherever faults in the automation system
may cause damage to persons or property,
external measures must be implemented to
ensure a safe operating state in the event of
a fault or malfunction (for example, by
means of separate limit switches,
mechanical interlocks etc.).

1 EZ800 Control Relay
Target readership EZ must only be installed and wired up by trained electricians
or other persons familiar with the installation of electrical
equipment.
A specialist knowledge of electrical engineering is needed for
commissioning and creating circuit diagrams. When
controlling active components such as motors or pressure
cylinders, parts of the system can be damaged and persons
put at risk if EZ is connected or programmed incorrectly.
Proper use EZ is a programmable switching and control device and is
used as a replacement for relay and contactor control circuits.
EZ must be properly installed before use.
EZ is designed to be installed in an enclosure, switch cabinet
or distribution board. Both the power feed and the signal
terminals must be laid and covered so as to prevent
accidental contact.
The installation must conform to regulations for
electromagnetic compatibility (EMC).
The power up of the EZ must not cause any hazards arising
from activated devices, such as unexpected motor startups or
power ups.
Improper use
EZ should not be used as a substitute for safety-related
controls such as burner or crane controls, emergency-stop or
two-hand safety controls.

EZ800 Control Relay
MN05013004E12
Overview EZ800 Control Relay is an electronic control relay with:
• Logic functions,
• Timing relay and counter functions,
• Time switch functions
• Arithmetic functions
• PID controllers
• Operator and display functions
EZ800 Control Relay is a control and input device rolled into
one. With EZ800 Control Relay you can create solutions for
domestic applications as well as for tasks in machine and
plant construction.
The integral EZ-NET network enables the connection of up to
eight EZ-NET stations to form a single control system. Each
EZ-NET station can contain an individual circuit diagram. This
allows the design of systems using fast controllers with
decentralized intelligence.
Circuit diagrams are connected up using ladder diagrams,
and each element is entered directly via the EZ display. For
example, you can:
• connect make and break contacts in series and in parallel
• switch output relays and auxiliary contacts,
• define outputs as coils, impulse relays, rising or falling
edge-triggered relays or as latching relays,
• select timing relays with different functions:
– on-delayed,
– on-delayed with random switching,
– off-delayed,
– off-delayed with random switching,
– on and off delayed,
– on and off delayed with random switching,
– single pulse,
– synchronous flashing,
– asynchronous flashing.

• use up and down counters,
• count high-speed signals:
– up and down counters with upper and lower limit values,
–preset,
– frequency counters,
– high-speed counters,
– count incremental encoder values.
• compare values,
• display any texts with variables, enter setpoints
• process analog input and output values (DC units),
• process additional inputs and outputs,
• use 7-day and year time switches,
• count operating hours (operating hours counter),
• communicate via the integrated EZ-NET network,
• provide closed-loop control with P, PI and PID controllers,
• scale arithmetic values,
• output manipulated variables as pulse-width modulated
signals,
• run arithmetic functions:
– add,
– subtract,
– multiply,
– divide.
• track the flow of current in the circuit diagram
• load, save and password-protect circuit diagrams
If you prefer to wire up EZ800 Control Relay from a PC, then
use EZSoft. EZSoft allows you to create and test your circuit
diagram on the PC. EZSoft enables you to print out your
circuit diagram in DIN, ANSI or EZ format.
